575-03-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 575-03-1, name is 7-Hydroxy-4-(trifluoromethyl)coumarin, molecular formula is C10H5F3O3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: The appropriate bromoketone (6a-o) (1.7 mmol) and triethylamine (1.6 mmol) were added to as olution of either7-hydroxy-4-methyl-2H-chromen-2-one 4 (1.4 mmol)or 7-hydroxy-4-(trifluoromethyl)-2H-chromen-2-one 5 (1.4 mmol) in THF (20 mL). The mixture was stirred at room temperature for 24h, filtered and the solvent was evaporated under reduced pressure.The solid residue was purified by column chromatography eluting with DCM/MeOH 9:1 to afford (7a-n) and (8a-o).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 575-03-1, 7-Hydroxy-4-(trifluoromethyl)coumarin, other downstream synthetic routes, hurry up and to see.
